MemSpy

MemSpy is a very simple memory information tool that comes with a basic interface and only a few details regarding system performance.
Once installed, MemSpy launches a tiny window that shows the requested information and nothing more, along with a small graph that helps you track the overall performance of the machine.
Although the number of features is fairly limited, MemSpy can report free and used RAM, free and total Swap file, CPU usage and Windows uptime, all through the basic interface we were talking about.
While you cannot resize the window to better fit your desktop, MemSpy doesn't even feature interface customize options, so what you see is what you get and nothing more.
The application works on every single Windows version on the market, but don't expect to find plenty of features after launching it for the first time. There's not even a help manual included in the program, so in case you're a beginner and wish to find out more information on the displayed data, you have no other option than to search the Internet.
Of course, since it's such a lightweight tool, MemSpy remains very friendly with hardware resources all the time, working just fine on all Windows workstations.
As a conclusion, MemSpy is only a decent application, providing almost the same amount of tools like a Windows gadget. It places a small screen on the desktop to show RAM information, without any optimization feature or any kind of customization setting.
